One of these toolholders is included with the P/N 2250 quick-change tool post system. If you are working with boring tools of different sizes or depths that you would like to have pre-installed in interchangeable tool holders to take full advantage of the quick-change nature of the system, it might be a desirable to have a second holder on hand.

For another way to use inserted tip tools with the quick-change tool post see P/N 2295.
